Viscoelastic analysis of inpile stress relaxation (LWBR Development Program)
Technical Report
·
OSTI ID:7095498
A description of in-pile stress relaxation on the basis of a Maxwell-Kelvin linear viscoelastic model is developed from the assumption of a mechanical equation of state combined with creep characteristics observed in in-pile creep experiments. A previous proposal that in-pile stress relaxation can be represented by this viscoelastic model is further substantiated by an analysis of in-pile stress relaxation data for Almar 362, a maraging stainless steel. The data show general agreement with the type of stress relaxation curves predicted by the model. In addition, consideration of the effect of strains introduced in the specimens prior to the in-pile relaxation helps to resolve an apparent discrepancy in the temperature dependence of different sets of Almar relaxation data.
